Xobni (the word inbox spelled backwards) makes your inbox and address book smarter. First launching to the public in 2008, Xobni, and its’ Smartr product suite, discovers all the people you’ve ever emailed, called or SMS’d, and creates complete and social profiles that are instantly searchable. Profiles include a photo, job title, company details, email history as well as updates from your contacts on LinkedIn, Facebook, and Twitter. Products for Gmail, Android and iPhone are available under the Smartr brand; and Xobni is available for Outlook and BlackBerry. Xobni Pro is the premium offering that connects all Smartr and Xobni products.
Xobni was acquired by Yahoo in July 2013.
